Jonathan writes: IIO new device support, features, cleanup for 7.3 Includes a merge of 7.2-rc2 to pick up the changes around mod_devicetable.h and reduce resulting conflicts around includes. New device support ------------------ adi,ad3530R - Add support for the AD3532R and AD3532 16 channel DACs. adi,ad4080 - Add support for the AD4883 ADC. adi,ad5686 - Add support for AD5313R, AD5317R, AD5674, AD5687R, AD5689, AD5689R DACs over SPI - Add support for AD5316R, AD5674, AD5697R and AD5696 DACs over I2C - Significant driver refactoring prior to these additions, partly to reduce bus traffic and to add triggered buffer and gain control support. An earlier set added support for missing supplies, reset and LDAC GPIO. adi,adf41513 - New driver to support this PLL frequency synthesizer that runs up to 26.5 GHz. - Included infrastructure to handle higher precision attributes with extensive tests adi,ltc2378-20 - New driver supporting LTC2338, LTC2364, LTC2367, LTC2368, LT2369, LTC2370 LTC2376, LTC2377, LTC2378, LTC2379 and LTC23980 ADCs with both high speed capture via appropriate backend and conventional triggered buffer SPI capture. invensense,icm42607 - New driver for this IMU. mediateck,mt6323 - New driver for this PMIC ADC. microchip,mcp47a1 - New driver for this I2C 6 bit DAC. nxp,mcf54415-dac - New driver for this DAC found in NXP SoCs. qst,qmc5884l - New driver for this 3 axis magnetometer. Included dt vendor entry for qst. qst,qmc6308 - New driver for this 3 axis magnetometer. sensiron,slf3s - New driver for this liquid flow sensor. Includes adding IIO_VOLUMEFLOW channel type. st,vl53l1x - Refactors to improve readability. ti,ads112c14 - New driver supporting the ADS112C14 and ADS122C14 ADCs. These bring some new ABI for input chopping, particular useful for resistive sensors like thermocouples or Wheatstone bridges. - Support CRC8 detection of corruption on the bus. - Support buffered reads. ti,tmp117 - (trivial) Add support for the tmp119 temperature sensor. xilinx,versal-sysmon - New ADC driver for this block found on various FPGAs including various bus interfaces, threshold and oversampling support. dt binding updates ------------------ new shared bindings - excitation-channels and excitation-current-nanoamp allow per channel specification of currents used for resistive sensor measurement. - reference-sources property to allow selection of a per channel reference. rockchip,saradc - Add RV1106 which is compatible with the RV3588. Features -------- buffer-dmaengine - Allow cyclic buffers, useful for repeating sequence generation with DACs. devantech,dmard09 - Implement read back of channel scale - previously interface always returned an error. hid,sensors-als - Enable separate channel scaling for hardware that supports it. invensense,timestamp library - Various precision improvements. invensense,icm42600 - Add support for hwfifo watermark interfaces. taos,tcs3472 - Support wait time and sampling frequency control. Cleanups, minor fixes --------------------- Minor cleanups not mentioned at all in this summary such as white space fixes or typos. Affecting various drivers - Cleanup of conditionals that had no affect. - Drop some runtime pm local wrappers as now runtime_pm does the mark_last_busy part inside the put, these provide no useful code deduplication or readability advantages over directly calling the runtime_pm functions. - Return 0 from write_raw() on success. - Use of dev_err_probe() to simplify code and sometimes provide useful info for deferred probe debugging. - Drop some redundant error prints where the called function already provides information on errors. - Make some read only arrays in functions static. - Fix up missing handling of regcache_sync() errors. - Drop some false kernel-doc markings. - Add missing MODULE_DEVICE_TABLE for some of_match_id tables. - Use local variables for things like the struct device to shorten and improve readability of code. - Drop some unused structure elements. - Reorder dds.h macro parameters to be inline with others. - Header reorders and IWYU. Often part of a more significant series. - Remove abstractions designed to allow a driver to support multiple device types, when they have been around a long time and only the original part showed up. - Initialize spi_device_id arrays using member names following dropping of driver data from drivers that didn't actually use it. - Catch up with i2c_device_id tables added since previous effort to use named initializers for all those. - Use kernel types in a few places instead of standard C ones or bare unsigned. Misc - Update Xilinx AMS maintainer. - Update email address for Maxwell Doose. - Update email address for Siratul Islam. - Update email address for Tomasz Duszynski and re-add Tomasz to various maintainer entries.

iio: temperature: hid-sensor-temperature: switch to non-devm iio_device_register()

2026-07-11T22:28:04+00:00

Avoid using devm_iio_device_register(), as this driver requires explicit error handling and teardown ordering. With devm_iio_device_register(), IIO device remains registered until the devres cleanup phase. However, driver's remove() callback removes the sensor hub callback and trigger support. This can create a race window where IIO device is still visible and read_raw() requests are issued. These requests might call sensor_hub_input_attr_get_raw_value(), which waits up to 5 seconds for a response from the sensor hub callback that has already been removed. Add an explicit iio_device_unregister() call in the teardown path to ensure deterministic cleanup, so that userspace can no longer access the device once backend resources begin to be dismantled.

iio: temperature: hid-sensor-temperature: use common device for devres

2026-07-02T17:27:29+00:00

kmemdup() is used for memory that is logically tied to the HID platform device, even though the driver binds into the IIO framework. Using &indio_dev->dev for devres allocations works functionally, but it results in two separate devres ownership trees—one for the HID platform device (pdev) and another for the IIO device (indio_dev). The devres framework is intended to have a single, well-defined parent device. Since the memory originates from HID sensor probing and is not IIO-specific, &pdev->dev is the correct and logical owner. Switch to using the platform device for devm_kmemdup() so that all resources are released deterministically and consistently.

drivers/iio/temperature/Kconfig has a dedicated MLX90635 option, but the Makefile currently builds mlx90635.o under CONFIG_MLX90632. This means enabling CONFIG_MLX90635 alone does not carry its provider object into the build, while enabling CONFIG_MLX90632 unexpectedly also builds mlx90635.o.
